ONE-FOURTH TO BERTHOLD WEIL, OF NEW BOTTLE-SEAL.

To' all whom it may concern.-

Be it known that I, ADOLPH G. KAUFMAN, a citizen of the United States, residing at New York, in the county and State'of New York, have invented a new and useful Bottle-Seal, of which the following is a specification.

This invention relates to seals for bottles; and especially to that class which are used but once; and the object thereof is to provide a seal, first, in which rubber may be used as the gasket, means being provided to efiectually shut ofi the rubber from coming in contact with the contents of the bottle; second, to provide a seal which can be secured to a bottle and bring the central portion. thereof in close contact with the inner side of the lip without causing the breakage of a large er centa e of the bottles; third, to provi e a seal w hi ch may be spun on a bottle and have the required strength in the locking skir't while using a comparatively thin metal; and, fourth, to provide ready means for opening the bottle without a tool.

I accomplish the objects of my invention by the construction illustrated in the accompanying drawing, in Which A Figure 1, is a central, vertical section of m improved seal about to be applied to a bott-le; Fig. 2, is a similar view of the same applied; Fig. 3, is a top plan view of a seal showing means to 'stifien the central part; Fig. 4,

is'a similar view showing different arrangement of the stiffening means; Fig. 5, man

elevation of the seal applied to a bottle, showing special opening means; Fig. 6, is a blank, on a smaller scale, showing a modified form of special opening means; and, Fig. 7, is a modified form of blank, on same scale as Fig. 6.

1n the accompanying drawing the several parts of my invention are indicated by nu merals-of reference; and in practice I provide a seal corn risin" a metal cap 8, which may be of any esirerlmaterial, but preferably of aluminium; and which when formed ready to be applied to a bottled, as 9, consists of a central part 10, a concaved annular part 1 1,

viewing from the inside, an annular asket seat 12, on an elevated plane, and a skirt 13, provided with a step'14, leavin about half, or a little less than half the skirt 15, below the step. Within the seat 12, is mounted the gasket 16, which is preferably composed of rubber, although I do not confine myself to the use of that material. a

When the seal is ready to apply to a bottle, the parts are so prop'ortioner that when the part 11, is in contact with thelip 17, of the Owe, the P and kirt, 13, will be ele h vated above the normal position they will,

occupy when the seal is secured in place so that-when the capping tool is applied, the pressure block of the tool will cause the part 11 to become more concave, bending around the interior of the lip, and dra ging the skirt of the cap down until it is at a? normal level,

zontal, or practically horizontal by the cap-- ping tool, to occupy the position shown in Fig. 2, causing the lower edge of the part 11 to come in-very close contact with the 1nte rior of the lip, and eiiectually cutting off the contents of the bottle from thegasket 16. In order that the part 10 may be held in the position driven by the tool, I may provide ribs, as indicated at 20, in" Fig. 3, or 20 in Fig. 4.

By providing the step 14, when the part 15 of the skirt is spun in under the shoulder 18, the strain of locking will be on the part of the skirt 15, from the bottomthereof to the rib without a tool I have provided a lip, or pro jection 21', which may be cut from the portion of the metal intervening between the blanks in stamping the same from. sheet metal, and on one sideof which I form a slot 22, which extends upward adjacent to the rib 19; and by taking hold of this projection, the metal may be torn along the line indicated by the dotted line 23, until sufficient metal-has beentorn away to allow the removal of the cap. This can be readily done especially if the cap is composed of aluminium; and if composed of aluminium it is also 45 and skirt adapted to be brought into a locking understood that the bottle may be opened by cutting out the central part 10.

In Fig. 6 I have shown a modification in that the metal of the blank is slotted on. each side of the lip 21', as indicated at 22, and 24. By slottin the metal on each side of the lip, the seal W1 1 be opened by tearin the metal up across the top of the cap, as wi I be understood.

In Fig. 7, I have shown a modified form of special opening means, in which the ed e of t e blank is slotted, as shown at 25, an the end 26, is turned 11 on itself, so that it may bereadily en aged y a finger nail, and the part 27 r'nay be raised so that it can be seized to tear the metal as illustrated in Fig. 5. It will thus be seen that I have provided a seal which can be'brou ht in close contact with I the interior of the ip of the bottle; and, at the same time, as the part incontact with the lip is bent while in contact with the lip in or der to' bring the skirt down into locking osition, the force causing the metal to ben will be sufiicient to relieve any sudden shock which otherwise might come directly on the ii of the bottle causing the bottle to break.

e mode of applying, too, will cause the part 11 to' contact more closely with the lip wthan could practically be done in another manner, especially as the lips of the bottles as ordinarily constructed, are very uneven.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States, is

1. A bottle seal comprising a cap and gasket, said cap being provided with a concaved part adapted to contact with the lip of a bottle, and an elevated gasket seat and skirt adapted to bebrought into a locking position after said part is in contact with the lip of a bottle.

2. A bottle seal cornprisin soap and gasket, said cap being provide with a central art, a concave part ada ted to en age the lip of a bottle, and an e evated gas :et seat position after said concave part is in contact with the lip of. a bottle, su

, stantially as described.

3. A bottle seal. comprising a cap and gasket, said cap being provide with a concaved art adapted to contact with the li of I abott e, an elevated gasket seat and s t adaphted to be brought nto a locking position by t e bending of said concaved art incontact with the ip of a bottle, sai skirt being stepped, as and for the purpose described.

states caved annular part adapte to contact with the lip of a bottle, and a gasket seat elevated above said concaved part, as and for the purpose set forth.

5. In a bottle seal, a ca having a concaved annular part adapte to contact with the lip of a bottle, a gasket seat elevated above said concaved part, and a stepped skirt, as and for the purpose set forth.
